Review on BULVACK 300 Amp Circuit Breaker with Manual Reset | Car Marine Trolling Motors Boat ATV Power Protection Fuse | Audio System 12V-48V DC (300A) by Michael Zambrano

As a master electrician with 45 years of experience, I have installed more equipment than I can count. In all these years this is the first circuit breaker I've broken. Due to the limited space I planned to use it in my RV between the inverter and the batteries. As it turns out, I put the old 200 amp fuse back in. Due to lack of time I don't have time to exchange it before departure. I was disappointed with how easily this 150 amp circuit breaker broke when tightening the mounting screws. I would not recommend it.
